Control charts are to be kept on the thickness measurements for a process that rolls 10-gage copper sheets. The current specification in the sheets is 0.1360+0.0020 inch. After collecting 25 samples of n 5 measurements at approximately half-hour intervals, the data were used to determine Σ L:3.421 inches and R.-0.044 inches, with i1 to 25. Assume that the quality...

control chart for x bar and sigma chart
Control charts for x bar and s are maintained on a quality characteristic. The sample size is n=4. After 30 samples, we obtain3030∑ ¯xi=12,870and∑ sj=410i=1i=1A. Find the centerline and three sigma control limits for the s chart.B. Assuming that both charts exhibit control,estimate the aprameters μ and σ.
